In this paper we extend the analysis of by comparing delay in protocols using retransmission and packet encoding for bidirectional unicast communication over a satellite channel, where the signal propagation delay is significant. We derive results on the total sender-receiver delay based on analysis and computer simulation for a Bernoulli packet arrival distribution.
Distributed beamforming is a form of cooperation among nodes in a wireless network to efficiently deliver a common message to a distant receiver. The critical requirement to achieve electromagnetic coherence is to synchronize the initial phases of all local oscillators, introducing minimal overhead and complexity. In the paper we introduce random, deterministic and hybrid algorithms, all based on...
Real-time GNSS receivers usually track the navigation satellite signals by means of code and carrier loops. In previous works we derived optimum loop filters and introduced the UFA discriminator to improve the PLL response to acceleration steps expected in launching vehicles. In this paper we present a data detection strategy based on the Per Survivor Processing (PSP) technique to use a four quadrants...
